/**
* @class vtkChartSelectionRepresentation
* @brief representation for showing selections
* in chart views.
*
* vtkChartSelectionRepresentation is a representation showing selections in
* chart views. It works with vtkChartSelectionRepresentation (namely
* vtkChartSelectionRepresentation::MapSelectionToView) to map the input
* vtkSelection to selection form that the view can understand and then passes
* it alone to the vtkPVContextView.
* For client-server cases, this class also handles delivering of the selection
* to all "rendering" nodes.
